[Class 40 (ii)] [Also in Group XX] A combined picture-projecting apparatus and gramophone, particularly for advertising, has a continuously recurring series of pictures, e.g. an endless film supplied to the projector, and a repetition mechanism for the tone-arm of the gramophone. The film 9, Fig. 1, is driven intermittently through the projector 10 by Maltese-cross mechanism 11 driven by a flexible shaft 7 coupled to a motor 3, which also drives the gramophone 4 and the known automatic repeat-mechanism 5. The period of operation of the repeat-mechanism and the playing period of the record are exact multiples of the time of exhibition of individual pictures so that the machines work synchronously indefinitely. The projector may exhibit the pictures in a viewing aperture 12 by mirrors 13, 14, the loud-speaker 15 for the gramophone being mounted behind the mirror 14. The mirror 13 may be mounted on a sliding door which may be opened so that the projector 10 may exhibit the pictures directly on a linen screen. The gramophone and motor are housed in the lower part of a casing 2 access to which is obtained by a door 1. According to a modification, the operation of the repeat-mechanism is controlled by means driven by the picture film driving gear. In this modification the flexible shaft 7, Fig. 2, coupling the gramophone turntable to the film-driving sprocket 8, drives an endless chain 17 carrying a cam 19, which at the end of the series of pictures, projects a plunger 20 in the end of a lever 21 into the path of a cam 24, whereby the lever is actuated to lift the tone-arm 6 and return it to initial position. The film may carry more than one set of pictures and the gramophone may have known record-changing mechanism so that one record may correspond to one set of pictures, or so that different records may accompany the same set of pictures. The loud-speaker may be located at a distance from the casing containing the gramophone and the picture-projecting apparatus.

Title: Improvements in or relating to electromagnetic waveguide transmission systems
IPC: H01P1/02
Filed: 1958-08-22
Abstract: 845,492. Waveguides. WESTERN ELECTRIC CO. Inc. Aug. 22, 1958 [Aug. 29, 1957], No. 27042/58. Class 40(8). A bend in a circular waveguide for the transmission of H 01  mode energy is constructed so that it has a gradually increasing curvature in the neighbourhood of its junction with the straight sections of the guide. Such a bend minimizes mode conversion losses due to the curvature discontinuities which occur at the extremities of a bend having a constant radius of curvature. It is stated that optimum transmission characteristics are obtained if the curvature function, e.g. the curvature expressed as a function of axial waveguide length, is the Fourier transform of a Tschebyscheff polynomial of infinite degree. The bend may be constructed by constraining a waveguide 43 to the shape of a template 41 and clamping the guide in position with clamps 42. In a modification, the curvature k, Fig. 6A, is arranged to increase linearly to a maximum value and then to decrease linearly to zero. Such a bend may be obtained by bending the waveguide around a fixed pin having a radius negligible compared to the axial length of the bend. In a further modification, the central portion of the bend has a constant curvature k 0 , Fig. 6B, and a linearly diminishing curvature to either side of the central portion. This bend may be constructed by bending the guide around a pin 61, Fig. 7, of radius R 0  = 1/ko so that the portion of the guide in contact with the pin acquires a constant curvature k 0 . Where the elastic deformation limits of the guide are exceeded the bending method shown in Fig. 5 is employed. The waveguide may be of the type in which degeneracy between the H 01  and E 11  modes has been reduced by known techniques. The length of the portions of tapered curvature should be of the order of, or longer than, the longest beat wavelength associated with the structure, i.e. 1 #2#/## where ## is the smallest difference in phase constant between the H 01  and unwanted higher modes. Specifications 764,737, 845,253 and U.S.A. Specifications 2,751,561, 2,774,945 and 2,779,006 are referred to.

Title: Improvements in the manufacture of anthraquinone derivatives
IPC: C09B1/40
Filed: 1934-09-27
Abstract: Anthraquinone derivatives containing a free amino group and an acidylamino group wherein the acidyl radicle corresponds to an aliphatic monocarboxylic acid containing at least two carbon atoms are prepared by partial acidylation of the corresponding di- or polyaminoanthraquinone by means of the free acid as the sole acidylating agent or partially hydrolyzing the di- or polyaminoanthraquinone acidylated to a higher degree.  In the partial acidylation process no agents should be present which are capable of transforming the acid into an acidylating agent of another type such as the acid halide or anhydride.  By this process partial acidylation is effected without contamination by substantial quantities of a completely acidylated product.  The partial hydrolysis operation is most suitably effected by means of concentrated sulphuric acid at a low temperature not exceeding about 10 DEG  C.; the progress of the hydrolysis can be followed by examination of the colour of the product.  In examples: (1) 1.4-diaminoanthraquinone is refluxed with glacial acetic acid for 40--50 hours; (2) 1.4 - diacetylaminoanthraquinone (prepared by treating the diamino body with a mixture of acetic acid and anhydride) is treated with concentrated sulphuric acid at about 10 DEG  C. for 5--7 hours; the monacetyl-1.4-diaminoanthraquinone obtained by either process is suitable for dyeing cellulose acetate materials.  Other materials specified as obtainable are acidyl derivatives containing free amino groups of 1.4.5 - triamino-, 1.4.5.8 - tetramino-, 1.5-diamino-4.8-dioxy-, 1.8-diamino-4.5-dioxy-, 1.4-diamino-5-oxy-, 1.4-diamino-5.8-dioxy-, 1.4.5-triamino-8-oxy-, and 1.4-diamino-5-oxy-6-chloranthraquinones (the last-named body is prepared by reduction of 6-chlor-1.4.5-trioxyanthraquinone and amidation with ammonia as described in Specification 343,444), the acidyl radicles being acetyl, propionyl or butyryl.
